1. The drama is based on the Guangdong province's "Thunder Anti-drug" special action 20 12.29 in 2003, which shows that the "drug first village" was overturned overnight and restores the whole story of this extraordinarily serious drug trafficking case in China. The plot takes the anti-drug action of Li Fei and his son as a double clue, and tells the story of two generations of anti-drug police who are not afraid of sacrifice and desperately tear open the intricate drug network woven by local drug dealers.

2. An overseas transnational drug trafficking group colluded with local criminals in Dongshan to produce underground ice poison on a large scale, thus selling a large amount of ice poison to inland provinces and overseas in China and making high profits. In this complex and dangerous environment, the anti-drug police, represented by Li Fei, spared no expense to tear open the huge poison net woven by local drug dealers and umbrellas, broke through numerous puzzles, and cleared the way for the smooth development of the "Thunder Anti-drug Special Action".
